I don't know that I agree with this sentiment. I do think you should have a couple basic L shaped tension wrenches. I am partial to the twist-flex variety. The circular tension tool has been reviewed on this site by Varjeal. Have a search for that thread. I really feel that different tensioners will give you different feedback and can make a significant difference in picking. Start with the L shapes, but keep in mind the others for the future.
